Best student loan repayment plan for $30k

On $30k of student loans the plan sets both the monthly payment — $427 on RAP against $341 on the standard 10-year plan at a $75k income — and what the loan costs in total. There are two answers, because Public Service Loan Forgiveness discharges the balance tax-free after 120 payments and everyone else pays to the end or to a taxable write-off. Every figure below is a full year-by-year projection: single filer in Texas, 28 years old, income growing 4% a year, 6.5% federal loans taken in 2026, run through age 60 so a 30-year RAP term and its forgiveness tax fall inside the window.

The plans compared for $30k

Payments start from a $75k salary and rise with it. RAP is the only income-driven plan open to loans taken from July 2026; IBR stays available to older loans; PSLF is a program layered on either one. "Total" is every payment plus the tax charged in the year a balance is forgiven.

$30k student loan monthly payment by income

The standard payment never moves — $341 a month for 120 months, whatever the salary. The income-driven payments do: RAP takes 1–10% of AGI by $10,000 band, IBR 10% of income above $23,940. The last two columns give each income its own verdict, from the same projections as the table above.

The same ladder at every balance, with the crossover income where RAP stops being the lower payment, is on RAP vs IBR; the RAP formula by AGI and dependents is on the RAP calculator.

Every balance at a $75k income

Each row is its own set of projections, not a scaling of this page's. At $75k the standard plan is cheapest at 9 of the 11 balances and RAP at 2: at $30k RAP's income-based payment is at or above the ten-year payment, so the loan clears sooner with less interest; at $40k it starts below the ten-year payment but rises past it with income and still clears the loan before year 30. The full balance-by-income matrix runs the same comparison at four incomes.

What decides it

• Public service. PSLF discharges whatever is left after the 120th qualifying payment, tax-free, so the lowest qualifying payment wins and a large remaining balance is the point, not a problem. Here the payments clear the loan at 34, so PSLF has nothing left to forgive. The plan-by-plan version is on best repayment plan for PSLF.
• Not public service, balance large next to income. RAP's payment is a share of AGI, not of the loan; unpaid interest is waived, the balance falls by at least $50 a month (the payment, if less), and whatever remains at 30 years is forgiven and taxed as income that year. On $30k at $75k the payments clear the loan at 34, so nothing is forgiven — see the forgiveness tax bomb calculator.
• Not public service, payment affordable. The standard plan's $341 a month retires $30k in ten years with $10,877 of interest, the least of any plan. Refinancing to a lower private rate lowers that interest but permanently gives up income-driven plans, PSLF and federal discharge protections.

Educational comparison, not advice. Figures are one persona — single filer in Texas, 28 years old, income growing 4% a year, 6.5% federal loans taken in 2026, run through age 60 so a 30-year RAP term and its forgiveness tax fall inside the window — run through Coastline's projection engine; a different income path, state, filing status or rate changes them. IBR is modelled on its post-2014 terms (10% of income above 150% of the poverty line, capped at the 10-year standard payment, forgiveness at 20 years); RAP's per-dependent reduction counts children aged 0–23. Repayment rules change often — verify current terms with your servicer and studentaid.gov, and model your own balance in the calculator.

When a smaller balance argues for simply paying it off

At a balance that is modest relative to your income, the standard ten-year plan is usually the right default. The monthly payment is manageable, and because it is the shortest of the common schedules, it also minimizes the total interest you pay over the life of the loan. Paying the balance down is a guaranteed, risk-free return equal to its interest rate, which is a genuinely good use of money once you have captured any 401(k) match and cleared higher-rate debt like credit cards.

Income-driven repayment would lower the monthly figure, but it stretches the term and adds interest, and on a balance this size you would almost certainly repay the loan long before any 20-to-25-year forgiveness could arrive. That makes the lower payment a convenience, not a strategy.

If you hold several loans at different rates, direct any extra dollars at the highest-rate loan first. Plan names and terms change from year to year, so confirm the current options before locking in.

The interest deduction that quietly lowers the real rate

Student-loan interest is one of the few deductions you can claim without itemizing. Up to an annual cap of $2,500 of the interest you actually paid comes off your taxable income, which means the effective rate on the loan is a little lower than the rate on the statement — the government absorbs a slice of it at your marginal tax rate.

The benefit phases out as income rises and disappears above a threshold, so it tends to help most in exactly the early-career years when a balance this size feels heaviest. It is also unavailable to anyone filing married filing separately, which is worth knowing before choosing that status for other reasons.

None of this changes which plan to pick, but it does narrow the gap between the loan's rate and what the same dollars might earn invested. Confirm the current cap and phase-out range, since both are adjusted over time.
